How to Use a QR Code Generator
QR (Quick Response) codes are two-dimensional barcodes that smartphone cameras can scan instantly. They've become essential for restaurant menus, event tickets, product packaging, and contactless sharing.
What Can QR Codes Contain?
- URLs — Direct users to a website or landing page
- WiFi credentials — Let guests join your network by scanning
- Contact info — vCard with phone, email, address
- Email addresses — Pre-filled compose window
- Phone numbers — One-tap calling
- Plain text — Any message or data
QR Code Best Practices
- Test before printing — Always scan-test with multiple phones
- Use sufficient size — At least 2×2 cm for close-range scanning
- Maintain contrast — Dark code on light background works best
- Add quiet zone — Leave white margin around the code
- Use short URLs — Shorter data = simpler code = easier to scan
